Wedding budget

Hi guys! Recently got engaged and planning to get married sana December 2025. Currently have siguro 20k na savings na intended na now for wedding prep. Me and my fiancée’s combined earnings is at 70k/month lang huhu and our estimated gastos for everything na talaga is about 500k. Keri kaya ng 1 year na prep given our monthly income? Huhu and also, his parents pledged din for our wedding but fiancée refuses to accept kasi we want na kame lang sana gagastos. Also, I don’t come of a well-off family kaya wala talagang pledge na mangaggaling for sure from my parents, not that I’m expecting din. So i’m kinda worried kung kakayanin kaya namin :((( We contribute sa house expenses din and have insurance na 7k a month namin binabayaran. :(((

Edit: his parents pledged 200k. They insisted pero as much as possible gusto namin samin ang gastos huhu and our target is about 100-150pax

Edit2: thank you all sooo much for your suggestions, opinions and just everything!! 🥹❤️
